This invention relates generally to a system for controlling, conveying,and positioning a hose and discharge point thereof wherein the hose ismaintained in a safe and orderly fashion.

In the utilization of pneumatic hose employed in conjunction withpneumatic equipment, the hose generally is suspended in a looparrangement from an I beam so that the hose discharge point may be movedin accordance with the positioning of various air lifts. The looparrangement presently employed is clumsy and cumbersome and it has beenfound that the hose does not follow the trolley. Further, the system isinadequate because it has proven to be unsafe in that the hose may besevered or it may break loose from a coupling whereby a dangerousinstrument will be released as the hose whips through the air motivatedby escaping conveyed compressed gas.

It is one of the primary objects of this invention to provide an orderlymethod of handling any fluid conveying flexible hose between theconnection at the supply point and the connection at the discharge pointwhere the equipment is being served.

It is a further object of this invention to so control the hose byconfining the hose within a conduit system at all times during theoperation.

Further, the invention provides means for positioning the hose withinthe conduit according to the location requirements of the equipmentbeing served. The hose discharge point is free to move along thecomplete length of the conduit while the interior components within theconduit assure the orderly handling of the hose be tween the hose inletand hose discharge point. The invention finds particular utility whenemployed for supplying compressed air to overhead air motor hoists andpropulsion air motors. However, the teachings of this invention applyequally well to the control of any fluid conveying flexible hose.

A still further object of this invention is to provide a novel systemwherein a hose length is confined within a. conduit so as to removeunsightly exposed and disorderly loops of hose which are prone to catchand snag. It will be apparent that the conduit will provide a protectivehousing for the hose eliminating somewhat the corrosive effects of heatand fumes which may be present.

In accordance with the above stated objects, below is described thenovel system for controlling the conveyance of a discharge point of ahose wherein the hose [wherein the hose] is maintained in a safe orderlyfashion. The components of the system include the conduit, a length offlexible hose, a hose carrier, a hose guide, and a cable control systemconnecting the hose guide and hose carrier for maintaining desiredrelative positioning therebetween. I

Other objects and advantageswhich will become subsequently apparentreside in the details of construction and operation as more fullyhereinafter described and claimed, reference being had to theaccompanying drawings form- Re. 25,642 'Reissuecl Sept. 15, 1964 ice inga part hereof, wherein like numerals refer to like parts throughout, andin which:

FIGURE 9 is a sectional view taken substantially along the plane 99 ofFIGURE 3.

With continuing reference to the drawings, numeral 10 generallyrepresents the conduit system comprising this invention and including asubstantially square conduit 12 having an elongated rear opening 14. Itis contemplated that the conduit be manufactured of heavy gauge steel orextruded aluminum. However, the measurements of the conduit andparticular material utilized would vary depending on the size of thehose employed in the particular sysem. Design requirements would dictatethe particular dimensions and configurations of the conduit along withthe various components utilized. Still further, the flexible hoseemployed herein is a conventional hose capable of conveying thepressurized fluids required. Standard hose fittings and couplings may beutilized without exception. A hose inlet pipe 16 is fixed as by Weldingas at 18 to the conduit 12 and terminates in an elbow portion asillustrated at 20.

An initial system component is illustrated in FIGURE 4 wherein the hosecarrier 22 supporting a plurality of rotatable wheels 24 is showncarrying the hose discharge pipe 26 which communicates with a rightangle pipe portion 28 to be utilized in a manner more specificallydisclosed below. It is to be noted at this time that an aperture 30 runsthrough the length of the hose carrier 22. Particularly referring toFIGURE 3, it is noted that the hose carrier 22 is positioned within theconduit 12 whereby the various wheels 24 contact the conduit sidesallowing the hose carrier 22 to move within the conduit. The dischargepipe 26 extends rearwardly through the elongated opening 14 in theconduit 12.

A second basic component of the system includes a hose guide 32comprising a base member 34 having depending leg portions 36 and 38. Thehose guide 32 is adapted to move along the conduit on sliding legs 36and 38. Of course, any means may be utilized to provide a movablerelationship between the conduit 12 and hose guide 32. For instance,wheels, as illustrated at 24 in connection with the hose carrier 22, maybe employed. A pulley 40 is rotatably supported on vertical axis 42mounted on base 34. The pulley 40 extends rearwardly from the conduit 12through the elongated opening 14. A plurality of roller guides 44 arepositioned on the base 34 for guidance purposes to be more clearlycomprehended below.

A furtherbasic component of the conduit system includes the cablecontrol system which provides connection between the hose carrier 22 andthe hose guide 32. The cable control system includes initially a cable46 having sections 48, 50, 52, and 54. A hook 56 is so cured to aportion of the conduit 12 and fastens one end of the cable 46 thereto.Section 48 of the cable 46 then proceeds around a pulley 58 carried byhose guide 32, through section 50 around a pulley 60 fixed to theconduit 12, through section 52 passing below the base 34 of hose guide32 and through aperture 34! of hose carrier 22, around pulley 62 fixedto the conduit 12 at an end remote from the point where pulley 66 isfixed, through section 54 to hook 64 fixed to the hose carrier 22. Themanner in which the control cable system operates will be more fullydiscussed below.

A flexible hose 66 is coupled to-the hose inlet 16 in a conventionalmanner at 68. The hose 66 proceeds through the conduit around guiderollers 44 and around the pulley 40 of hose guide 32 and is coupled tothe pipe section 28 at coupling 7 0.

At least one of the guide rollers, marked 44 in FIG. 3 after the onewith the'section 9-9 line and in the direction of the hose carrier 30,provides a guide means exerting force on the hose '66 after the hose 66is reversed in direction by a reversing means including a reversing hoseguide pulley 40 (which reversed the hose 66 from the direction leadingfrom the fixed inlet 16 through an arc of approximately 183 desuch asthe first roller grees). The guide means, roller 44, tends to force thehose 66 to remain on the reversing pulley 4:0 during the reversingmotion thereon. The force exerted by the guide roller 44 against hose660r vice versaopposes any tension in'the hose (as would occur when airpressure is introduced into the hose 66) and directs and forces the hose66 back in the direction from the inlet 16 that it came from, that is,back towards the length of hose extending from the hose inlet 16 to thereversing pulley 40. The distance between the two lengths of hose 66,one length extending from the hose inlet to the reversing means andother length from the hose reversing means pulley 4-0 to the hosecarrier 22 is less at the hose guide means roller 44 than the maximumdistance between the twolengths measured across the loop of hose 66 atthe hose reversing means, across the diameter of pulley 40 in FIG. 3.This action helps maintain the hose 66 on the reversing pulley 40 andagainst the guide means, roller 44, and directs the hose in an orderlyfashion back to the conduit 12 and maintains the hose 66 in a straighterfashion and manner than would occur with loose loops and lack of supportand/ or guidance.

In the operation of this system, for instance when used in conjunctionwith an overhead air motor hoist on a monorail, the conduit isconstructed so as to be equal in length tothe service distance of themonorail. The conduit suspension is parallel'to the monorail and ispreferably supported from brackets as by welding. When attaching thedischarge point 26 of the system to the service inlet of a hoist beingserved, a standard flexible hose of a proper length to provide a loopbetween the conduit discharge and service inlet is utilized. In order toprevent any force from being'transmitted along this connecting hose, acable or chain of shorter length than the connecting hose is utilizedbetween the service inlet and the hose carrier 22. It will be apparentthat since the cable or chain is of shorter length than the connectinghose, it will transmit any force inducedby, any relative movement by theservice inlet to the hose carrier and no force will betransmittedthrough the connecting hose. Referring to FIGURE 3, assuming that aforce to the right is transmitted to the hose carrier 22. The force willbe :ransmitted from the hose carrier 22 along the hose 66 :o the pulley4t) and axis 42 thereof. -As the hose carrier 22 moves a particulardistance to the right, the hose guide 32 will move half that distance tothe right. Of :ourse, as hose carrier 22 moves to the right the hook 64Lttached thereto moves to the right and cable will pass hrough pulley62'and pulley 60 to compensate for pulley ?8 moving to the right. Itshould be apparent that thereore as the hose discharge point 26 moves tothe right, he hose length 66 will be maintained in a safe orderly ashionabout the pulley 40 and the hose 66 will not tend to loop, gather, orbunch to impede movement. If now, a force is transmitted to the hosecarrier 22 such that the hose discharge point 26 must move to the left,a force will be transmitted through section 54 of cable 46. The forcetransmitted through the cable 46 will pull the pulley 53 to the left andthereby of course carry the hose guide 32 to the left. Again, it will beapparent that the hose length 66 will remain in orderly fashion. Itshould further be apparent that the hose guide 32 moves half thedistance of the hose carrier 22 in either direction. It should beapparent therefore that herein has been disclosed a novel system forcontrolling the conveyance of a discharge point of a hose whereby thehose is maintained in a safe orderly fashion. Further, one skilled inthe art should realize that the hose is maintained in a safer moreoperative condition thereby minimizing expense and improving safetyconditions.

From the foregoing, the construction and operation of the device will bereadily understood and further explanation is believed to beunnecessary. However, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction shown and described, andaccordingly all suitable modifications and equivalents may be resortedto, falling within the scope of the invention as claimed.
